BALING PRESS.

SPECIFICATION forming part of Letters Patent No. 396,481, dated January22, 1889.

Application filed uly 5, 1888. $e1'ial No. 279,076. (No model.)

To all whom it may concern:

Be it known that I, DAVID L. HANNAY, of Grapeville, in the county ofGreene and State of New York, have invented a new and ImprovedBaling-Press, of which the following is a full, clear, and exactdescription.

My invention relates to baling-presses, and has for its object toprovide a simple, comparatively inexpensive, and very efficient machineadapted for pressing hay, straw, cotton, or other material into smoothbales of any required density and with economy of time and labor.

The invention consists in certain novel features of construction andcombination of parts of the baling-press, all as hereinafter describedand claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of my improved baling-press with the sweeppartly broken away. Fig. 2 is a side elevation thereof. Fig. 3 is abotton plan view of the press. Fig. 4 is a central longitudinal verticalsection of the press, taken on the line 1 l in Figs. 1 and 3. Fig. 5 isa plan view in horizontal section on the line 2 2 in Fig. 2. Fig. 6 is avertical transverse section taken on the line 3 3 in Fig. 1, and Fig. 7is a rear end view of the press-case.

The press-case A is made with a frame consisting of fourlongitudinally-ranging corner timbers, a a a a, which are connected bysuitable vertically and horizontally ranging cross timbers or pieces,against the inner faces of which are fixed suitable planks, a, formingthe floor of the baling-box B and bale-chamber C of the press. Planks aa fixed to the cross-timbers, form the opposite side walls of thebaling-box and bale-chamber, and one or more planks, a form the top wallof the balechamber, and also of the rear portion or half the top of thebaling-box, the front half or portion of which is open at b to allowhay, straw, or other material which is to be baled to be "fed into thebox B through a hopper, I), mounted on the press-frame at or above theopening I) of the box. The top wall, d of the press-case is fixed tothetwo top crosstimbers, a a, of the press-frame behind the feed-openingb; but in rear of these timbers the wall a is loose or free, and to thetop of the wall, at its rear end and immediately below the rear toparched cross-timber, a of the press-frame, is fixed a metal block, d,formed at its upper side with a couple of inclined or cam faces, againstwhich bear inclined or cam faces of the head (I of alever, D, which isjournaled on a pin or bolt, (1 passed downward through the frame-timbera the block (1', and the loose top wall of the bale-chamber. Vith thisconstruction. it is obvious that by turning the lever D in horizontalplane the outer or rear loose end of the bale-chamber wall a may belowered to contract more or less the bale-discharge open- I ing at therear end of the bale-chamber to regulate the resistance the pressed baleaboutto be discharged will offer to the rearward effective strokes ofthe plunger in forming a11- other bale in the baling-boxg hence thepress operates as a continuous baler, and by'adjusting the bale-chamberwall a bales of any required density or weight may be produced.

I am aware that balingpresses have heretofore been provided with ayielding wall at the baling-box and with screws adapted to adjust saidwall at its outer free end to regnlate the compression of the bales; butthe cam device for adjusting the yielding wall has material advantagesover the screw adjustment, in that it operates more quickly and but aslight turn of the cam-head lever is sufficient to relieve choking ofthe press or overstrain the horse operating it, and the attendant may,by noticing the position of the cam-lever, reset the yielding wall morequickly and easily than by the screw, and so accurately as to obviatethe necessity of weighing the bales every time the yielding wall iseased up temporarily while working the press.

The usual slots, 0, are provided in the presscase side walls forconvenience in tying out the bales.

The press-case will. or may be mounted on any suitable wheeled truck asshown in the drawings.

The plunger E, operating in the baling-boX to form the bales, isprovided with a pitman, F, the outer or front end of which is fittedwith a pin, f, which preferably provided with an anti-friction roller,f, which runs in a horizontal and transversely-ranging slot, g, made inthe metal head of the sweep G, which is provided with converging armsortirnbers, to the outer joined ends of which the horse for working thepress will be hitched. main portion of the sweep-slotg *anges about atright angles to and across a line which would bisect the sweeplongitudinally, and the opposite ends of the slot are formed asoutward]y-extending short slots or notches g g which communicate withthe main slot g, as shown best in Figs. 1, 3, and 5 of the drawings. Thesweep is journaled on a heavy bolt, II, 011 which above and below thesweep head and between it and the press-frame timbers are placed tubularwashers h 72, which hold the sweep in proper relation to the plunger andits pitman. (See Figs. 2 and at of the drawings.)

In operating the plunger the sweep will be drawn around in direction ofthe arrows at in Figs. 1 and 5 of the drawings, while the pitman-rollerf rests in the end slot or notch, g, of the sweep, and as the sweepreaches the position represented in Fi 1 the roller f will slip from theslot 9, and as the plunger reaches the limit of its rearward oreffective stroke the expansion of the pressed material, aided, it maybe, by the operation of a spring, presently described, will force theplunger backward, while the pitinan-roller is carried outward in theslot g toward the slot or notch g at the other end of the slot g, and aswill be understood from Figs. 1 and 5 of the drawings. As the sweep isswung around in the opposite direction the pitman-roller f will beengaged in and by the sweep slot or notch g and said roller f will slipfrom said notch as the plunger reaches the limit of its next inward oreffective stroke, and the plunger is carried backward by the expansionof the pressed material, and so on, the pitman-roller being engagedalternately by the sweep-head slots or notches g 9 and one effectivepressingstroke of the plunger being given at each half-turn of thesweep, or while the sweep is drawn in each direction, thus losing notime in pressing the bales.

The spring I, which assists the reboun d of the plunger, is placed on arod, J, which is preferably made square for about one-half of itslength, or that part of it which its a square hole in a bushing, K,which is journaled in a bottom cross-timber, a, of the press-frame, andthe rounded part of the rod is fitted to slide in another cross-timber,a and the spring I is placed on the rod between this timber a andawasher, i, which rests against the shoulders formed at the junction ofthe square and round parts of the rod. The forward end of the rod isprovided with a nut, j, which limits its rearward throw by the spring,and the rear end of the rod is provided with an upset or bent end orlug, j, which is adapted to be set in front of a pendent lug, e, on theplunger.

The bushing K has a stem, 7a, to which is connected one end of atransversely-rangingrod, L, which passes to one side of the presscaseand is provided with a loop or eye, I, forming a handle, which may begrasped to The i turn the bushing K, and consequently the rod .l, so asto throw the rod-lugj out of line with the plunger-lug c and allow theplunger to operate without effect of the spring I on it, as may bedesirable at times when pressing heavy bales and the force of expansionof the pressed charges of material is quite sufficient to full y retractthe plunger and pitman, or at other times when it is desirable ornecessary to clean the press after using it. This inoperative adjustmentof the spring-rod and spring is indicated in dotted lines in Fig. 3 ofthe drawings. \Vhen the spring is to be used, it is only necessary todraw out the rod L and turn the lugj of the rod J upward behind theplunger-lug c, as shown in full lines in Figs. and i of the drawings,and as the plunger is forced. rearward on its effective stroke the rod Jwill be forced rearward in its bearings K a and the washer or collar'iwill compress the spring I, and as the pitmairroller slips out ofeither of the sweep-notches g 9 along the slot g the spring will.forcibly expand to assist the expansion of the pressed material to carrythe plunger and pitman fully back ready to be again driven rearward bythe next or return stroke of the sweep after the next charge of materialhas been passed into the baling-box through the feed-opening b of thepress-case. Spring-retainers M are employed atthe sides of thebaling-box to hold the pressed charges of material by hook-heads m, toprevent undue expansion of it while the plunger moves back prior topressing the next charge of material. There may be two or more of theseretainers at each side of the baling-boX.

To ease the strain on the press-case, the plunger, and i is operatingmechanism, and to make smoother bales than could otherwise be done, Iemploy a folder at the rear sideof the baling-box openin This folder Nhas a triangular crosssectional form, (shown clearly in Fig. t of thedrawings) and is preferably journaled on a shaft, onwhich at oppositeends is held in angular bearing-plates O, the vertical portions of whichare let flush into the inner faces of the upper opposite corner timbers,a a, of the press-frame as guides to the plates, while the horizontalflange of the plates lies on top of these timbers and receives a bolt,P, which also passes through the press-timber a and carries at its lowerend a nut or collar, 2), between which and the timber a is placed on thebolt a spring, R, which normally presses on the nut 12 to hold the plate0 and the end of the folder N,which it carries, down to proper operativepositions. There being a plate, 0, bolt P, and spring R at each end ofthe folder l it is obvious that while the folder is free to turn on itsshaft 11, journaled in the plates 0, the folder free to rise bodilyagainst the tension of the springs R to prevent excessive pressure orfriction of the folder on the plunger E as it advances on its effectivestroke beneath the folder, and by adjusting the nuts 19 on the bolts Pthe resistance of the springs B may be regulated to control the downwardpressure of the folder as the nature or condition of the material beingbaled may require. A spring, S, fixed at one end to the top wall, a ofthe press-case, bears by its other end on top of one of the three flatsides or faces of the triangular folder and holds it normally in theposition shown in dotted lines in Fig. 4 of the drawings, or with one ofits sides about vertical and facing the fully-drawn back plunger andhanging quite a little into the baling-box in the path of the plunger orof the material being forced rearward by it. It is obvious that as theplunger moves rearward on its next effective stroke the folder will beturned partly around as it yields upward more or less, and until ittakes the position shown in full lines in Fig. 4:, or with its face,which had before been about vertical, now resting about horizontal orparallel with the top of the plunger, this turning of the folder havingpartly folded the loose material downward, and as the plunger in itsrebound passes the folder or slides from under it the spring S will turnthe next side of the folder forward into vertical position, as in dottedlines in Fig. at, and thereby cause the lowermost a11- gu-lar part ofthe folder to turn or fold down all the loose material smoothly into thebaling-box and hold it down until it is packed or pressed into the bodyof the -bale by the next charge pressed up by the plunger. The angularertically-yielding roller thus assures smoothness of the bales andgreatly facilitates the operation of the press by preventing a packingor wedging of material between the rear end of the feed-opening and theplunger.

The triangular rotating folder extending clear across the baling-box atthe rear of its feed-opening and preferably made vertically adjustable,as above described, is not to be confounded in its operation with aplain round roller-folder, or with a longitudinallyfluted roundroller-folder, whether they be vertically adjustable or not, as theround or fluted folders cannot effect so close or snug folding of thematerial to the charge last pressed up by the plunger as does thetriangular rotating folder, which folds all the loose material quitesquarely down from or with a comparatively sharp corner at and acrossthe top of the baling-box, and consequently assures more snugly pressedand smoother bales. Neither is the triangular rotating folder thestructural equivalent of a vertically-working folder at the rear of thefeed opening. Neither is the triangular rotating folder anticipated byshortpendent angular retainers which extend into the baling-box, but notentirely across it, as these retainers can have little effect in foldingdown loose material entirely across the baling-box against the chargelast pressed by the plunger, as will readily be understood.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a baling-press, the combination, with the press-case and a plungertherein having a lug or shoulder, e, of a rod, J, made flatsided andprovided with a lug, j, a bushing journaled on the press-frame and inwhich the flat-sided rod is fitted for endwise movement, and a springnormally forcing the rod backward, substantially as described, for thepurposes set forth.
